To solve this non-verbal reasoning question, we need to identify the pattern or rule governing the sequence of images and apply that rule to determine which option completes the sequence.

Let's examine the given sequence:

1. Notice that each figure consists of a central triangle and a surrounding pattern made up of arrowheads.
2. Observing the sequence, it appears that the arrowheads rotate clockwise with each step.
3. In the first figure, the arrowheads point upwards, in the second figure they rotate slightly to the right, continuing this rotation for the subsequent figures.

The pattern involves each arrowhead rotating clockwise in each step. Therefore, to complete the sequence, we need to continue the clockwise rotation pattern.

By observing the last figure in the sequence, predict the next step in rotation.

Now, compare the options to find the one that matches the expected rotation:

This option continues the clockwise rotational pattern correctly from the previous figure.

Thus, the correct answer is the fourth option.
